Specification of Letters Patent.

Patented Feb. 11, Tera.

To all whom it may concern:

Be it known that I, Jnssn SNYDER, a citizen of the United States, residing at Chicago, in the county of Cook and State of llinois, have invented certain new and use ful Improvements in "Window-Ventilators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and inexpensive,

yet a highly efficient and durable device for holding window screens in place, substantially flush with the outer side of the inner sash, provision being made whereby the screen holding means may be swung entirely out of the descending path of the upper sash, thus permitting lowering of said sash to the maximum for washing.

Withv the foregoing object in view, the invention resides in the novel construction and arrangement of parts hereinafter fully described, claimed and shown in the accompanying drawings.

Figure 1 is an inner side elevation of a portion of a window showing the application of the invention.

Fig. 2 is a horizontal section on the plane of the line 2-2 of Fig. 1.

Fig. 3 is a vertical section on the plane indicated by the line 33 of Fig. 1.

Fig. 4 is a view similar to Fig. 3 but illustrating the manner in which the screen holders may be swung outwardly when the screen is removed.

F ig. 5 is a detail horizontal section on the plane of the line 55 of Fig. 4.

Fig. 6 is a detail vertical section as indicated by the line 66 of Fig. 3.

Fig. 7 is a view similar to Fig. 3 but illustrating a different form of attaching means for the screen holder.

Fig. 8 is a horizontal section as indicated by the line 88 of Fig. 7.

Fig. 9 is a detail elevation, partly in section, showing a different form of hinge connection which may be employed.

In the drawings, above briefly described the numerals 1 designate the stiles of a window frame, 2 has reference to the sill of the frame, 3 and 1 indicate the lower and upper sashes respectively, 5 refers to the parting strips between the sashes, and 6 and 7 designate the inner and outer stop strips, respectively. All these parts are of common construction and form no part of the present invention except in their exist ing relation with the new features.

In the form of the invention shown in Figs. 1 to 6, the numerals l0 designate a pair of channel shaped screen holders each stamped from a single sheet of metal, each of said holders being so stamped at its closed side as to form an external rib 11 adapted to abut the outer side of the parting strip 5 as seen clearly in Fig. 2, the remainder of said closed side of the holder contacting with the edge of said parting strip. The two holders 1O removably receive the ends of a fine mesh ventilating screen 12 and are located to position said screen substantially flush with the outer side of the lower sash 3, whereby said sash may be located as seen in Figs. 1 and 3 to admit air, or may be entirely closed without removing the a screen. When positioning the screen in this manner, it necessarily is located in the descending path of the outer sash 1, and in a previous device which was placed upon the market, this was greatly objected to, due to the fact that the window washers could not lower the outer sashes for cleaning, but due to the nature of the present invention, this objection is entirely overcome.

Upper and lower arms 13 extend laterally from the outermost side flanges of the screen holders 10 and preferably have their outer ends turned downwardly to form pintles 14 receivable in sheet metal brackets 15 as shown most clearly in Fig. 6, said brackets being secured by screws or the like 16 to the outer stop strips 7. If desired, however, (see Fig. 9) the arms 13 may be provided with cross heads 14? movable in knuckles 15 above and below the arms and suitably secured to the strips 7 Regardless of the manner in which the arms are pivotally mounted, they permit the screen holders 10 to be swung outwardly as seen in Figs. 4. and 5, when the screen 12 is removed thus allowing the outer sash 4 to be completely lowered.

In the type of the invention shown in Figs. 7 and 8, the holders 10 which receive the screen 12* are stamped from a single piece of metal, and one side flange 11* of each holder is folded upon itself and extended laterally at 13 being hinged at 14: to a strip of metal 15 secured at 16 to the outer stop strip 7. The advantages of this form of the invention are the same as those above pointed out and-need:-not therefore be set forth in detail.

From the foregoing, taken in connection with the accompanying drawings it will be seen that although my invention is' of simple and inexpensive nature, it will be highly efficient and desirable, and Willovercome difficulties which have heretofore been encountered. Since excellent results are obtained from the details shown and described they may be followed in actual practice, but within the scope of the invention as claimed numerous minor changes may well be made.

I claim 1. In combination with a window frame and upper and lower sliding sashes mounted in said frame,a screen substantially flush with the outer side of the inner sash, screen holders removably receiving the ends of said screen, and means connecting said screen'holders to said" frame and permitting horizontal swinging of said holders out of the descending path of the upper sash;

2. In combination with a window frame, upper and lower sliding sashes mounted in said frame, and parting strips between said Copies of this patent may be obtained for sashes, a screen substantiallyflush with the outer side of the inner sash, a pair of stampedmeta'l channel shaped screen holders stamped at their closed sides to form external beads abutting the outer sides of said parting strips, the remainder of said closed sides of the the edges of said parting strips, and means hinge'dl'y connecting said screen holders with said frame and permitting horizontal swinging of said holders out of the descending path of the outer sash.

3. As an article of manufacture, a holder adapted window-screen, and means for hingedly-connectingv said holder to the window frame and permitting horizontal swinging-thereof out of the descending path of" the upper sash.

a. A structure as specified'in claim 3, said screen holder being of stamped. metal cha rnel shaped formation with its closed side stamped to form an eXter-nalbead to bear against the outer side of one of thewindow frame parting strips. I

In testimony whereof I have-hereunto set my hand. 7 JESSE SNYDER.
